The file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

PDF datasheet, 45.5 KB, for the 1N4934 fast recovery rectifier diode from the 1N4933 to 1N4937 family.

PDF of 314 KB named 25GQ045. The title resembles a semiconductor part number, so this is most likely a datasheet for a single component even though the index files it as…
